1 CVE-2013-4548 264 Bypass 2013-11-08 2013-11-30
6.0
None Remote Medium Single system Partial Partial Partial
The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address.
2 CVE-2009-2904 16 +Priv 2009-10-01 2014-08-08
6.9
None Local Medium Not required Complete Complete Complete
A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership.
3 CVE-2009-0689 119 DoS Exec Code Overflow 2009-07-01 2014-03-25
6.8
User Remote Medium Not required Partial Partial Partial
Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number.
4 CVE-2008-3234 264 1 2008-07-18 2014-08-08
6.5
User Remote Low Single system Partial Partial Partial
sshd in OpenSSH 4 on Debian GNU/Linux, and the 20070303 OpenSSH snapshot, allows remote authenticated users to obtain access to arbitrary SELinux roles by appending a :/ (colon slash) sequence, followed by the role name, to the username.
5 CVE-2008-1657 264 Bypass 2008-04-02 2014-08-08
6.5
None Remote Low Single system Partial Partial Partial
OpenSSH 4.4 up to versions before 4.9 allows remote authenticated users to bypass the sshd_config ForceCommand directive by modifying the .ssh/rc session file.
6 CVE-2008-1483 264 2008-03-24 2014-08-08
6.9
None Local Medium Not required Complete Complete Complete
OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs.
7 CVE-2007-0085 +Priv 2007-01-05 2008-09-05
6.0
Admin Local High Single system Complete Complete Complete
Unspecified vulnerability in sys/dev/pci/vga_pci.c in the VGA graphics driver for wscons in OpenBSD 3.9 and 4.0, when the kernel is compiled with the PCIAGP option and a non-AGP device is being used, allows local users to gain privileges via unspecified vectors, possibly related to agp_ioctl NULL pointer reference.
8 CVE-2006-6730 2006-12-26 2008-09-05
6.6
None Local Medium Single system Complete Complete Complete
OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2.
9 CVE-2004-2760 16 2004-12-31 2009-01-29
6.8
User Remote Medium Not required Partial Partial Partial
sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.
10 CVE-2004-1653 2004-08-31 2008-09-10
6.4
None Remote Low Not required Partial Partial None
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS.
11 CVE-2002-2180 +Priv 2002-12-31 2008-09-05
6.8
Admin Local Low Single system Complete Complete Complete
The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.
12 CVE-2001-1585 287 Bypass 2001-12-31 2010-06-24
6.8
None Remote Medium Not required Partial Partial Partial
SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file.
13 CVE-2001-1145 2001-08-17 2008-09-10
6.2
Admin Local High Not required Complete Complete Complete
fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.
14 CVE-2000-0092 2000-01-19 2008-09-10
6.2
Admin Local High Not required Complete Complete Complete
The BSD make program allows local users to modify files via a symlink attack when the -j option is being used.
